Description
Technical field
The invention belongs to medical art, be specifically related to a kind of anti-apoptotic Mcl-1 protein inhibitor and application thereof.
Background technology
Essence and the basic process of cancer generation development are just progressively disclosed, and have become the dominant direction of antitumor drug research for its molecular targeted new type antineoplastic medicine that development mechanism occurs.In recent years, some are using the relevant key protein of tumor cell differentiation apoptosis as drug screening target spot, find efficient in target site of selectively acting, low toxicity, the new type anticancer medicine of high specificity has become the another new direction of current antineoplastic medicine research and development.
Bcl-2 family protein plays very important effect in apoptotic regulation and control.This family protein comprises the contrary albumen of two class functions: a class is anti-apoptotic proteins, comprises more than ten members such as Bcl-2, Mcl-1, Bcl-xl and Bcl-w; Another kind of is pro apoptotic protein, comprises Bax, Bak, Bad and Bim etc.The albumen such as Mcl-1 also exist the surface combination pocket of a BH3 by name, can with many short antiapoptotic factors, as Bax, Bad, Bim and Bak etc. combine and form heterodimer, suppress their short apoptosis function, cause apoptotic infringement [NatRevCancer, 2002,2:647-656].Research finds, in cell, Mcl-1/Bcl-2 protein abnormal expression is relevant with the generation of kinds cancer, nearly all malignant cell is high expressed Mcl-1/Bcl-2 albumen all, and normal tissue cell Mcl-1/Bcl-2 expression very low [JCellBio.2008,180:341-355; CancerRes, 2006,66:9636-9645].Mcl-1/Bcl-2 albumen has been develop the new drug target of of cancer therapy drug in the world, and its research and development mainly concentrate on and how to suppress Mcl-1/Bcl-2 protein active or reduce its expression, carry out the apoptosis of induced cancer cell.
At present, commercialized product is there is no with the antitumor drug that Bcl-2 family protein is target spot, what have three effect optimums is in clinical I respectively, II, the III phase, respectively: the AB-737 researched and developed by Illinoi State, The United States Alpert laboratory, the GX15-070 (K protein bound with Bcl-2 of GeminX company research and development
i=0.22 μM) and the AT-101 (K protein bound with Mcl-1 of Ascenta company of the U.S.
i=0.18 μM).But they are Shortcomings all, as GX15-070 has the cytotoxicity not relying on Bax/Bak, just therefore on the verge of being replaced.In addition, and the inhibit activities in body is on the low side, metabolic half life is short, continuous use easily causes many defects such as liver, nephrotoxicity.Therefore, explore and develop the medicine of safety, efficiently specific antagonist Mcl-1/Bcl-2 albumen, specificity inhibition tumor cell grows, and the injury of normal tissue cell is very little, finally realizes the target that safe, efficient, low misery is anticancer.
Summary of the invention
For the problems referred to above, the invention provides a kind of anti-apoptotic Mcl-1 protein inhibitor and application thereof.
A kind of anti-apoptotic Mcl-1 protein inhibitor and application, it is characterized in that described inhibitor is Esculetin derivant, its structure such as general formula is:

ivalue is between 0.2 ~ 15 μM.
An application for anti-apoptotic Mcl-1 protein inhibitor, by any one or a few compound of Esculetin derivant and chemotherapeutics by making pharmaceutical composition after mixing and being used for the treatment of cancer.
Described Esculetin derivant and paclitaxel make pharmaceutical composition and for the treatment of nonsmall-cell lung cancer, its mol ratio share is 1:5 ~ 10:1, and preferred molar ratio is 1 ~ 5:1.
Novel Mcl-1 protein inhibitor involved in the present invention, with 6 of plant origin, 7-dihydroxycoumarin is basic structure skeleton, by the multidimensional property assessment of the structure-drug effect of series compound, structure-safety, structure-ADME attribute and optimize, have developed above-mentioned novel Mcl-1 protein inhibitor, such inhibitor and the protein bound K of Mcl-1
ireach 0.204 μM, its inhibit activities and commercially available Mcl-1 inhibitor AT-101 (K
i=0.18 μM) activity suitable, even higher than TW-37 (K
i=0.26 μM) inhibit activities.In addition, such inhibitor and paclitaxel coupling significantly can increase the inhibit activities of paclitaxel to A549 cell.Meanwhile, such inhibitor also has the features such as drug-resistant protein, reversible tumor multi-medicine drug-resistant such as good, the easy absorption of safety and potent suppression P-gp, has good patent medicine prospect.
